Abstract
Description
- The present invention relates to an automatic drawn arc welding apparatus for securing nuts to metal surfaces and, more particularly, to an air feed weld gun with retractable piston that has a dual piston mechanism for supplying welding gasses and/or air to the nut hole during the welding operation.
- Traditionally, weld nut guns have a collet. The spring forces in a slit collet hold a weld nut during the welding operation. Often, weld spatter from the welding process coats the threads on a weld nut, leading to significant cost and time loses due to component rework.
- To date, automatic feed weld guns which provide a supply of welding gasses to the threads of the nut during the welding process have proven relatively successful. As shown in FIG. 1, these
prior weld guns 15 utilized aprimary piston assembly 16 which is driven within acylindrical working chamber 17. Theprimary piston assembly 16 drives a hollow first drivenpiston 18. The priorart weld gun 16 utilizes severalsealable passages 19 to provide welding gasses through the hollow first driven piston. To effectuate sealing off of the throughpassages 19, theprimary piston assembly 16 utilizes a second fixedpiston 20 disposed through theprimary piston assembly 16. Disposed between theprimary piston assembly 16 and thefixed piston 20 is a series ofseals 21. Over time, theseseals 21 have the tendency to leak, thus allowing compressed welding gasses from theair supply 22 to enter theback portion 23 of theworking chamber 17. This inhibits the ability of theprimary piston assembly 16 to return to its fully retracted position within thecylindrical working cavity 17. - A need, therefore, exists for an apparatus and system which can automatically feed a weld fastener such as a nut or a stud to a welding surface. The apparatus provides welding gasses to the threaded portion of the weld nut to minimize the chance that weld spatter material will be incorporated into the threads. A need further exists for an automatic feed weld gun with an improved return feature which is resistant to degradation caused by cycling of the weld gun.
- In one preferred embodiment, a blow feed weld gun for welding a nut to a metal substrate is disclosed. The blow feed weld gun has an air feed mechanism and a primary piston assembly. The primary piston assembly contains a primary piston assembly located within a cylindrical working chamber. The primary piston assembly is coupled to a first driven piston which is hollow and defines a passage which welding gasses can be delivered to the threads of a weld nut. Slidably disposed adjacent the first driven piston is a second interior piston. A second interior piston, which is coupled to the primary piston assembly, regulates gasses through an axial bore of the first driven piston.
- In yet another preferred embodiment, the second interior piston is disposed within the passage of the first driven piston. Movement of the second interior piston is regulated by a pin which engages a slot formed within the first driven piston.
- In yet another preferred embodiment, the regulating pin of the second interior piston engages a forward wall of the cylindrical working chamber to affect the timing of release of welding gasses into the passage of the first driven piston.
- Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
- The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
- FIG. 1 represents a blow feed weld gun according to the prior art;
- FIG. 2 is a cross-sectional view of the blow feed weld gun of the present invention with its primary piston assembly in a fully retracted position;

- The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
- FIG. 2 discloses a blow feed weld gun30 for welding a
nut 32 to a metal substrate. The blow feed weld gun 30 has anair feed mechanism 33 and a drive mechanism 41, which drives thenut 32 into thewelding collet 36. The drive mechanism 41 is formed by an outer sleeve 38 which defines acylindrical working chamber 40 axially disposed with respect to thecollet 36. The drive mechanism 41 further has aprimary piston assembly 42 disposed within thecylindrical working chamber 40. The drive mechanism 41 defines afirst working chamber 44 and asecond working chamber 46, separated by theprimary piston assembly 42, between arear wall 48 and aforward wall 50. Defined within theforward wall 50 is abore 52 which accepts a first drivenpiston 54. Disposed through the first drivenpiston 54 is anaxial bore 56. The first drivenpiston 54 is comprised of a fastener driver in the form of afluted tip retainer 58 which engages thenut 32 and abody portion 60. - The
fluted tip retainer 58 is comprised of afluted tip 62 which circulates pressurized air about the threads of thenut 32, and aninsert piston extension 64. Thefluted tip 62 has a defined fluted tip throughbore 63 and aninterior radius 68, and threadedportion 70. Theinsert piston extension 64 has a threaded firstexterior radius 72, secondexterior radius 74, and weldment base through bore 76 fluidly coupled to the fluted tip throughbore 63. Theinsert piston extension 64 defines a firstinterior radius 78, secondinterior radius 80, and thirdinterior radius 82 which also has a defined interior thread. The first of drivenpistons 54body portion 60 has a defined axial throughbore 84. The body portion axial throughbore 84 defines a first internal radius 86, secondinternal radius 88, and third internal radius 90. Apolymer insulating portion 92 is disposed between thebody portion 60 and thefluted tip retainer 58 and functions to electrically isolate the fluted tip portion from the rest of the blow feed weld gun 30. - The
body portion 60 further defines a transverse throughair passageway 94 and defined throughslots 96 and mountingflange 98 which functions to mount the first drivenpiston 54 to theprimary piston assembly 42. - Disposed within the second
internal radius 88 of the body portion axial bore is the secondinterior piston 100. A secondinterior piston 100 is slidably moveable from a first closedposition 102 to a second open position 104 (see FIG. 8). In the closedposition 102, a secondinterior piston 100 functions to close the transverse throughair passageway 94. In theopen position 104, the secondinterior piston 100 allows air or welding gasses to pass through the transverse throughair passageway 94 into the body portionaxial bore 84. - The second
interior piston 100 further defines a throughpassage 105 which accepts apin 106 therein. Thepin 106 is further disposed within the defined throughslots 96 of thebody portion 60, and allows the secondinterior piston 100 to move from its first closedposition 102 to itsopen position 104. Thepin 106 acts as a mechanism to move the secondinterior piston 100 with respect to the workingchamber 40. The pin further engages theforward wall 50 as will be described later. - Further defined within the body portion axial bore is a
spring member 107 which axially engages therear portion 110 of the secondinterior piston 100. Disposed on the opposite end of thespring 107 is theflanged piston plug 108 which couples the spring member to theprimary piston assembly 42. Theflanged piston plug 108 has a definedbase 109 which functions to stabilize theflanged piston plug 108 within theprimary piston assembly 42. Theflanged piston plug 108 further has abody portion 100 having a circumference approximately equal to the circumference of thesecond drive piston 100. Thebody portion 100 is further disposed within the secondinternal radius 88 of the body portion axial bore 84. Theflanged piston plug 108 functions to compressspring 107 between theflanged piston plug 108 and the secondinterior piston 100. This enables the spring to normally bias the secondinterior piston 100 into itsclosed position 102 as defined by thepin 107 in the defined throughslot 96. The firstinterior piston 100 has a bearing surface 101 which engages seat 103 defined in theaxial bore 56. - Immediately adjacent to the
base 109 of theflanged piston plug 108 is a plurality ofspring washers 111 which function to bias theflanged piston plug 108 in a first forward position 112. Thespring washers 111 are held in place by a throughpin 113 disposed through a transverse throughpassage 114 defined in theprimary piston assembly 42. - Referring generally to FIG. 2, which shows the
primary piston assembly 42 of the blow feed weld gun 30 in its fully retracted position, air pressure has been introduced into the first workingchamber 44 throughair passage 120. In this position, anut 32 is feed into the receivingportion 122 by theair feed mechanism 33. As can be seen, air or welding gas pressure coming through theair supply line 124 is generally blocked by the primary piston assembly. - FIG. 3 depicts the
fluted tip 62 of theprimary piston assembly 42 engaging theweld nut 32 and forcing it into theweldment collet 36. As can be seen, theprimary piston assembly 42 has been moved from afirst position 126 to anintermediate position 127 by increasing the amount of pressure in the second workingchamber 46. Pressure is delivered into the second workingchamber 46. It should be noted that theair feed line 124 is closed off by the first drivenpiston 54. In theintermediate position 127, the secondinterior piston 100 is biased into its forward position byspring 107.Pin 106 is biased forward within throughslot 96 to position the secondinterior piston 100 to fluidly seal the transverse throughair passageway 94. - FIG. 4 depicts the blow feed weld gun30 of the present invention having the
primary piston assembly 42 in a secondintermediate position 130. In the secondintermediate position 130, thepin member 106 engages theforward wall 50 of the cylindrical workingchamber 40. Thepin 106 functions to stop the forward movement of the secondinterior piston 100. At this point, transverse throughair passage 94 is fluidly coupled toair supply line 124. It should be noted, however, that transverse throughair passageway 94 is sealed from theaxial bore 56 of the first drivenpiston 54 by the secondinterior piston 100. - As is shown in FIG. 5, as the
primary piston assembly 42 moves forward toward theforward wall 50,spring 107 is compressed and the first drivenpiston 54 moves thenut 32 into its forward position. As the first drivenpiston 54 is being pushed forward by theprimary piston assembly 42, the secondinterior piston 100 is held in place by the interaction ofpin 106 on theforward wall 50. At this point, transverse throughair passageway 94 is fluidly coupled to both theair supply line 124 and theaxial bore 56 of the first drivenpiston 54. - Referring generally to FIGS. 6 and 7, the
nut 32 is shown in its fully extended and weld position within thecollet 36. The transverse throughair passage 94 is fully aligned withair supply 124, allowing an unrestricted passage of the air or welding gas through theaxial bore 56 of the first drivenpiston 54. A controller (not shown) then activates a valve (not shown), which allows air to travel from theair supply line 124 into theaxial bore 56 of the first drivenpiston 54. As is shown in FIG. 7, the air or welding gas travels down through theaxial bore 56 until it reaches acone member 136 of thefluted tip 62. The cone member andfluted tip 62 function to disperse and circulate the air or welding gas within the threadedportion 138 of thenut 32, thus protecting the threads during the welding process. At this time, full pressure in input into the second workingchamber 46. Current is applied to thecollet 36 to effectuate welding between thenut 32 and the base material (not shown). During the welding procedure, air or non-combustible gas such as nitrogen, helium, air, or argon are inputted throughair supply line 124. It should be noted that the axial bore also may serve to place welding gasses within theshroud 140 of the blow feed weld gun 30. - As best seen in FIG. 8, upon completion of the welding sequence, air pressure is applied through
air supply 142 into the first workingchamber 44 of theload tube 40. This forces theprimary piston assembly 42 backwards away fromwall 50, allowing the secondinterior piston 100 to fluidly seal transverse throughair passageway 94, thus closing the fluid connection between theair supply 124 and theaxial bore 56. Additionally, thefluted tip 62 is withdrawn from the nut allowing disengagement of the blow feed weld gun 30 from thenut 32. Theprimary piston assembly 42 travels backwards until it reaches therear wall 48 of the load tube 40 (shown in FIG. 2). - The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
